it's similar. in a mainstream distribution with a desktop environment, updates can typically be configured to notify you or install automatically. it's common for those updates to now also include third-party sources like flathub.

upgrades (to a next point release or major version) are different, some can be fairly straightforward--others, not so much. and those upgrades will be more frequent, as the "lifecycle" for most linux distributions is shorter than windows' 10 years.
